The answer would be each pair of sandals costed $14
$14+$14=28+$3=$31
Answer: (a) e ^ -3x (b)e^-3x
Step-by-step explanation:
I suggest the equation is:
d/dx[integral (e^-3t) dt
First we integrate e^-3tdt
Integral(e ^ -3t dt) as shown in attachment and then we differentiate the result as shown in the attachment.
(b) to differentiate the integral let x = t, and substitute into the expression.
Therefore dx = dt
Hence, d/dx[integral (e ^-3x dx)] = e^-3x
Answer:
yes
Step-by-step explanation:
Use substitution method
3(2)+14=2(10)
6+14=20
20=20
Hope this helps. Have a nice day you amazing bean child.
